How’s this for a morning eye-opener? Well into this morning’s column, Cindy Adams drops this bombshell: “More ‘Sex in the City’: Can a sequel actually be in the pipeline? Producers have already been diddling with a follow-up script because, in advance, they believed this movie would be a hit. They figured a franchise, which could stretch over two more movies. That if Kim Cattrall’s private parts can hold out.” Hey, kiddies, don’t blame me! The hack responsible for writing and directing SATC, Michael Patrick King, coyly told Variety: “The actresses are great, and if the gods smile and people are still interested, why not?” Meanwhile, ace prognosticator Steve Mason’s final weekend box-office forecast at Fantasy Moguls has raised his prediction from $30 to $35 million, while he thinks “Indiana Jones” will easily hold onto the top spot with $50 million. Over at our corporate cousin Rotten Tomatoes the overall critical consensus is at 58 percent — they count anything under 60 as rotten — while among their “top critics” it rates as 62, thanks to effusive notices from David Edelstein, Owen Gleiberman and Carrie Rickey. The latest heavy hitters to skewer the interiminable film (which I gave 1.5 stars) include Mahola Dargis, Anthony Lane and Roger Ebert. I incorrectly stated a couple of days ago that “SATC,” which is rolling out on a bijillion screens at 3,285 locations, was the weekend’s only wide opening. Mase thinks “The Strangers,” a horror movie with Liv Tyler that Kyle gives half a star to, will be lucky to scrounge up $10 million.
